I did install Rockford Fosgate R169X2in front door, Memphis Audio PRX27 in dash & R1675X2 in the rear doors, still with stock radio.
Sound did improved a lot, bought it from Crutchfield.com
finally done a couple of days ago, had spare clamps/aluminum at home to complete the job. It was FREE of cost.
It does sound much better than the closed valves, however in the future, will do muffler/valve delete.

prices went down starting at $1,389.75.
I do have Kooks headers/cat-less down pipes on my Redeye, with stock muffler and really sounds great!
btw, Kooks products are very good in sound and finish.
at this moment NOT planning on installing headers on my Trail Boss, prefer muffler delete/CAI.
